1

What does NMR stand for

Nuclear magnetic resonance spectroscopy

2

How does NMR work?

If a nucleus has an odd number of nucleons then it can act as a tiny magnet

H nuclei oppose a magnetic field when it is applied thus reducing its strength

3

What is NMR spectroscopy used for?

To identify the structure of a compound

4

Number of peaks= ?

Number of H environments

5

What is the extent to which a magnetic field is altered measured in?

ppm

6

What is the scale for NMR called?

Chemical shift

7

What is the reference molecule for NMR?

Tetramethylsilane

8

What is the standard molecule for NMR?

Tertramethylsilane

9

Draw the skeletal formula of the molecule all shifts are compared to in NMR


CH3
|
H3C-Si-CH3
|
CH3

10

Why is tetramethylsilane used to

H

11

Identify a solvent in which molecules can be dissolved before obtaining its proton NMR spectrum

CDCl3
